Object-oriented programming; nested simulation; reflective simulation; SIMULA; application to transitic systems

The paper deals with nested simulation, i.e. simulation of systems that contain simulating elements, and especially with reflective simulation, i.e. simulation of systems that contain elements simulating their own environment. The problems of nested simulation and their solutions are outlined and so far implemented nested simulation models are described. Nested simulation is important in design and modeling of systems existing in advanced computerized society.
